IMPROVEMENT IN GRAIN-DREES.

Be it known that I, JULIUs Ds BABY, of Offenbach, in the'Duchy ofV Hesse Darmstadt, Germany, have invented u. new and improved Malt-Kiln and Grain-Drying Machine; and I do herebydeclare that the following is a'full, clear, and exact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to a new and improved kiln for drying mult and grain.

The invention has forits object the evnporuting and carrying off of moisture contained in the melt or grain, 'by u. very simple and compact means, which will operate very expeditiously and without injuring the malt or grain by undue or excessive heat.

To this end, the invention consists in carrying the mult or grain, by means of a series of endless conveyors, over u series of perforated plates placed one above the other, and impelling u current of hot air up through said perforated plzites and conveyers, and through the malt or grain in transit, the hot air absorbing or taking up the moisture and carrying it o` from the kiln. In the accompanying sheets of drawings-- Figure 1, Sheet No. 1, is a side vi'ew of my invention.

Figure 2, a vertical section of the same, taken in the line a: z, iig. 3.

Siuiiler letters ofreference indicate like ports:

A represents e. casing, which is double walled. The inner well c may be of sheet metal, and a; dead-air space. allowedv between the two walls or said space-mcy be illedtwith any non-conducting zuateriel, to prevent the radiation of heat from the casing. 'This casing is placed directly overa. foundation, B, into which. a. hot-air' pipe, C, posses, or o flue, D, from a. furnace; The ilue D is of sinuous or zigzag form, in order to obtain as.

great' a. heet-radiating surface as possiblel and the hotair pipe C hasanoblong-slot, (LX, made ln one or both sides of it to admit of broad stream of hot air being forced out from it to pass upthrough the casing, When the lutter is heated by the pipe C, the -hot air is forced through it by means of a fen, or other equivalent Ineens, and when the flue D is used, the .casing is heated simply bythe radiatioll of heat therefro'ins- The latter is used when a gentle heat is required, and the former, when a. greater heat is required in order to accomplish the work-r Within the casing A. there is placed n series of endless carriers, E, which may be constructed each of two endless chains b, with slats, c, tted between them. The endless chains 6 work around pulleys d 'on shafts F in the casing, and the bearings of 'scid shafts are mode adjustable, in order that the carriers my be tightened in the event of the same becoming slack or loose by use. These carriers have o. horizontal position in the casing, and they are placed one directly above the other, as shown more particularly in fig. 3, with s. perforated plate or screen, G, placed underneath cach; und under the upper part of the top carrier E thereis placed a solid or unperforated metal plate, H, while perforated plates I are placed under the upper parts 'of the curriers under# neath. The inner wall a, at its upper port, is perforated, as shown at e; and these zperforations4 form a commuuication between the interior of the casing and tubes IX at the outer side of the casing, (see figs. 2nnd 3.) The endless carriers E all move in the direction indicated by the arrows in hg. 3, motion being communicated to the samethrough the medium of gearing j', shown i'n fig? 1. Thecasing is provided with doors g, placed one opposite or in line with each carrier, in order that the progress ofthe drying may be inspected from the bottom to the top of thevoasing, und thermometers placed therein to designate the temperature.

The malt or groin to be dried is deposited on the upper carrier E, and is conveyed along on`A the plate H by the plates c of said carrier, and deposited upon the pcrforatedplate Gr underneath, until it arrives ut an opening, h, in G, through which it drops upon the perforated plate I of the carrier underneath, and is carriedclong on said plate I, and deposited upon the perforatedl plate G underneath, from whence it is dropped, through an opening, upon the perforated plate I below, to be conveyed along by the carrier below, and so on until the malt or grain reaches the bottom of the casing, where it is discharged at eX.

The hot air, in passingu'p through the casing, carries'ci all the moisture through the tubes IX, audit will he seen that the malt or groin is subjected gradually to the heat, as the temperature of the casing or kiln increases gradually, of course,-from its top downward, and the malt orl grain also s made to pass over a large area within a small compass.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- In a malt and grain-.drying machine, the outer woodenzcase A, innermetallic oase a, with' an interposed air-space, the adjustable endless-chain scrapers E, perforated' plates G I, imperforate plate H, pipes IX, and zigzag hot-ir ue D, when constructed, arranged, and. operating as described for the Ipurpose specified.
